@ Kodename47 - I'm running the OFT values for PI/DI ratios, nothing changes above 2400 RPM at full load. That was something I thought of because I thought I'd seen people with that kind of problem before. Load limits are as follows, and I thought sufficient, but who knows - I may not understand the table correctly (Also honestly not sure if I copied these from somewhere, or if I just increased them across the board for boost):
800 1000 1200 2000 2200 2400 2500 3000 3200
1.2 1.4 1.6 2.0 2.2 2.4 2.6 3.0 3.2
@ steve99 - Thank you, thank you, thank you for suggesting logging pulsewidths. I thought of the possibility of valve overlap causing it, but I couldn't fathom a way to test for that. I'm guessing that depending upon sensor outputs, cam timing is adjusted such that on one pull I could have more overlap than another?
Also, is DI max delivery the same as "DI Quantity Maximum"? Currently has a value of .9 up through 4800 RPM and then .75 from 5200-6400, and .82 from 6800 up.
Thank you both again for the help! |
in DI max quantity make the entire table 1
vavle timing should be consistent if load vs rpm same conditions.
if your on stock Port injectors you want about 35% port in the pi di tables at all load\rpm above load 1. You can run say 50% port below say 3000 rpm but over load 1 over 3000 you want 35% in port
if you run more port that 35% on stock injectors atvhighbtpm\load it will run out of capacity
max port pulse width about 15 max di about 6 ms
